10 RoboMower - Safety Features 1. Child Guard / Safety Guard This menu option offers a safety feature to help prevent children or others not familiar with the safe operation of the mower to operate it freely. 2. Lift Sensor There is a sensor located on the front caster wheel of the mower. In the event the front of the mower is raised approximately 1-inch from its resting position on the ground during blade operation, the blades will stop rotating immediately (< 1 second). 3. Sensor Equipped Bumpers The front and rear bumpers are equipped with contacts that will activate when the mower strikes a solid, fixed object when that object is at least 6-inches in vertical height from the supporting surface of the mower. When the bumper sensor is activated, the mower will stop movement in that direction and reverse itself away from the obstacle. In manual blade operation, bumper activation will stop the rotation of the blades immediately (<1 second). 4. Emergency Stop Switch Located on the top outer surface of the manual controller, red in color. Pressing this button at any time during operation will stop all mower movement and stop the rotation of the blades immediately (<1 second). 5. Automatic Mode Recognition The RoboMower is designed so that it cannot be operated in the manual mode while the Manual Controller is in its pocket and it cannot operate in the automatic mode while the Manual Controller is removed. 6. Two-Step Operator Presence Control While in manual mode, it requires two independent finger actions in order to engage the mower blades. Once engaged, the mower blade button must remain depressed to continue blade operation. Once released, the two-step engagement process must be repeated. 7. Electronically Controlled Charging System The RoboMower is equipped with an on-board charge control system. This allows you to keep the Power Supply connected at all times, even after the battery is fully charged. The control system will prevent an overcharge to the battery and keep it fully charged and maintained for the next use. 8. Sealed Power Pack The power pack that operates the RoboMower is completely sealed and will not leak any type of fluids, regardless of position. In addition, the power pack contains a one-time-use fuse in the event of a short-circuit or power malfunction. 9. Perimeter Switch and Perimeter Wire The RoboMower cannot operate without a perimeter wire installed and activated through the Perimeter Switch. In the event the Perimeter Switch is turned off or otherwise fails to function, the RoboMower will stop operating. Likewise, should a break in the perimeter wire occur the RoboMower would again stop operation. A break in the perimeter wire prior to operation will prevent the RoboMower from operating. The RoboMower can only operate within the boundary of the perimeter wire. 10. Auto-Off Perimeter Switch The auto-off feature of the perimeter switch shuts down the perimeter switch operation after approximately 5 hours of continuous operation. This is typically 1 to 2 hours after which a fully charged Power Pack will need to be re-charged. This helps to prevent unauthorized persons from attempting to re-start the RoboMower after it has completed its operation. 8

11 11. Over-Current Monitoring Protection Each of the three blade motors and each of the two wheel drive motors are monitored continuously during operation for any situation that may cause these motors to over-heat. In such event, the RoboMower will stop operation of at least that motor and possibly the mower itself and indicate that the motor is cooling down. While unusual, this may happen when the mower is put in grass that is severely overgrown; the underside of the mower is clogged from poor cleaning maintenance; the mower has encountered an obstacle that is unable to activate the bumper sensor preventing it from moving; or a problem landscape area has caused the mower to get stuck and is preventing it from moving. 12. Automatic departure warning alert When the mower is scheduled to depart the Docking Station automatically per a scheduled time, a warning buzzer and the operating lamp will activate 5 minutes prior to departure. This is a warning notification to clear and inspect the area. WARNING!! This warning symbol will be found at several points throughout the pages of this manual. It is intended to highlight an important safety, warning or cautionary message. Please pay particular attention to these areas and be sure you fully understand the message before proceeding. 9

13 A Basic How It Works A small wire, called the perimeter wire, is placed around the perimeter of the lawn and any other areas where you do not want the mower to enter. A small signal is generated from a device attached to the perimeter wire, called the Perimeter Switch. When turned on, this signal is carried through the perimeter wire, creating what we define as a virtual wall. The virtual wall is visible only to the RoboMower, keeping the RoboMower where you want it, on your lawn. The perimeter switch must be turned on to activate the perimeter wire before the RoboMower will operate. Perimeter switch turned on to generate signal Virtual wall, visible only to the Robomow 11

14 Chapter 1 Perimeter Wire Setup 1.0 Where To Start In order to determine the best location to begin the setup, it is best to first make some basic decisions based on your lawn. While many lawns can be effectively cut during the course of one single, most lawns and homes are not laid out in such fashion to efficiently allow the RoboMower to operate freely all over the lawn. Because of this, the typical setup of the perimeter wire may actually be two separate areas or zones, as they are called. For each zone that is set up, allow for placement of one Perimeter Switch for that zone. Find a convenient spot outside the perimeter of each zone, but a location that is relatively easy for you to access. It is recommended to place the perimeter switch in a dry and sheltered location. Consider placing the perimeter switch near shrubs or bushes to hide them. Now, knowing the Perimeter Switch location, you can begin the setup by starting the wire at each of the Perimeter Switch locations. In figure 1.1, the front yard and the back yard are physically separated by fence. The fence prevents the RoboMower from moving freely between the front and the back. In this example, there are two zones, one for the front and one for the back. Knowing ahead of time that two zones will be needed will help the setup go smoothly. 1.1 Using The RoboRuler The RoboMower includes a ruler style measurement stick called a RoboRuler that is used to help position the perimeter wire along walls, fences, sidewalk, driveways, flower beds and other perimeter zones. There are two basic measurements that are used on the RoboRuler. The shorter distance is used along perimeter edges where the area outside the immediate perimeter (about 12 inches/30 cm) is free of obstacles and is the same relative height as the perimeter edge. The longer distance is used along perimeter edges where the area outside the immediate perimeter has obstacles or differences in the height along the perimeter edge. See Figure

15 Note: Use the short distance of the RoboRuler to set the wire position around the obstacle while creating a Perimeter Island (See section 1.8). Area outside perimeter - same basic level and free of obstacles. Area outside perimeter - has a wall as an obstacle. Perimeter wire position Perimeter wire position Short distance Figure 1.2 Using the RoboRuler Long distance 1.2 Perimeter Wire Setup Puncture the plastic covering of the perimeter wire with your finger and feel around inside the center of the wire spool for the end of the wire. Pull the wire end out of the plastic covering. The plastic covering is designed as a dispenser for the wire, so do not remove the wire spool from the covering. If an additional wire is required in order to complete the set-up, use the wire connectors to connect between the two wire ends, as explained in chapter 8.6. IMPORTANT: It is necessary to first read this chapter (Perimeter Wire Setup) before starting to layout the Perimeter Wire, in order to be aware of all setup rules and instructions. Starting at the location of the Perimeter Switch, begin pulling the perimeter wire out of the plastic covering as you walk along the area of the lawn you are setting up. Be sure to leave enough wire at the beginning, where the Perimeter Switch will be located. Leave no less than 5 feet (1.5 m) of wire at the beginning of the setup. After removing enough wire within a given section, use the RoboRuler (see section 1.1) to identify the correct placement of the wire. Initially place a minimum number of pegs to fasten the wire down. You will want to test the proper position of the wire for the edge mowing process and you may find some areas where you will need to move the wire position slightly. See section 2.8 for details on testing. You can lightly insert pegs into the ground by hand to hold the wire temporarily in place before driving the pegs to the ground level with a hammer. WARNING!! Damage to the eye is possible. Use proper eye protection and wear appropriate work gloves when hammering the pegs. Hard or dry ground may cause pegs to break when driving them in. In extreme cases, watering the lawn where the pegs will be driven can be beneficial. 1.3 Fastening The Wire To The Ground It is not necessary to bury the perimeter wire, though you may do so if you wish, up to 3 inches (7.5 cm). Small pegs or stakes are supplied with the RoboMower and they are used to fasten and hold the perimeter wire to the ground, below grass level. They resemble a small tent stake. When properly fastened to the ground, the wire and pegs will soon disappear under the growth of new grass. The pegs simply hold the wire in place at the ground level to allow for the grass to grow over it. Pegs should be driven at distances between one another that will keep the wire down below the grass level and prevent it from becoming a tripping hazard while in the process of being covered with grass growth. See Figure 1.3. Remember, you want to test the wire setup for edge mowing before you fill in the additional pegs. See section 2.8 for details on testing. 13

16 Perimeter Wire Add pegs in to pull the perimeter wire down to the ground surface, below the grass tips. Tip! It is recommended to water the ground prior to pegging the wire. Figure 1.3 Pegging the Perimeter Wire 1.4 Corners & Sharp Turns Care must be taken not to create a corner sharper than 90 degrees when setting up the perimeter wire. A corner sharper than 90 degrees can cause the RoboMower to lose track of the perimeter wire. In situations where a corner may require a wire placement of less than a 90-degree angle, placement can be adjusted using several angles to avoid this. See Figure 1.4. Correct corner setup, using several angles to avoid an angle of less than 90-degrees Lawn area Incorrect corner setup Figure 1.4 Proper Setup in Sharp Corners 90 degrees 1.5 Narrow Areas And Narrow Passes There is a limitation to the width of an area the RoboMower can effectively navigate through in order to move into another larger, but attached area. A narrow pass is defined as an area that narrows down substantially from the initial width and in which the RoboMower must pass through in order to access and cut other zones, an hourglass shape. The minimum distance for an effective narrow pass is 5.5 feet (1.7 m) between perimeter wires. The larger a pass can be made, the better access RoboMower will have between the zones. This will greatly improve the effectiveness and efficiency of the mower. See Figure 1.7. For an area that is narrow in width, but does not provide access to another section of the same zone, there is a minimum working distance of 5.5 feet (1.7m). Figure

17 1.6 Defining Obstacles-Perimeter Islands Many obstacles can be left in the lawn without consideration to excluding them using the perimeter wire. The basic rule of thumb is that the obstacle must be at least 6 inches (15 cm) high from the ground and the obstacle must be relatively rigid. Good examples of these kinds of obstacles include many trees, phone poles and power poles. When obstacles like this are encountered in the lawn, it is easiest to allow the RoboMower to bump into them, causing the bumper sensor to activate and assist in navigating around them. Young, sapling aged trees are not good examples, as they are not very rigid. Other obstacles that are not rigid and at least 6 inches high (15 cm) must be protected from the RoboMower using the perimeter wire. This is done as part of the setup process and is commonly referred to as a perimeter island. Good examples of these types of obstacles are flowerbeds, islands, small trees and low bed edging. The RoboMower is designed to easily work in the lawn with both types of obstacles, however, for the most gentle and silent operation, it is preferable to demarcate all fixed objects in and around the working area. If you are unsure about a particular obstacle, it is best to exclude it with the perimeter wire. It will have no effect on the efficiency of the mower and can later be removed if not needed. To create a perimeter island, take the wire from the perimeter section closest to the obstacle and peg the wire around the obstacle, returning back to the same spot of the perimeter. There are two keys to setting up the perimeter wire to exclude an obstacle; 1) place the wire going to the obstacle from the perimeter and the wire going from the obstacle to the perimeter adjacent to one another. This area is between the obstacle and the normal lawn edge where the perimeter wire is set up; and 2) follow the direction of installation when going to the interior of the lawn to exclude an obstacle. While the picture in figure 1.5 may appear to have the wires leading to and from the island set up with a space between them, this is for illustration purposes only. A proper placement of these two wires is to have them touching one another, but in no event should they be farther than 1/8 of an inch (3 mm) apart from one another. For the best results, place both wires under the same peg when placing them in the lawn around obstacles. Placement of the wires as described allows for the signal in the two wires to cancel, but only in the area where they are installed adjacent to one another and touching. By canceling the signal in this section, the RoboMower is free to cross this area but will still recognize the signal of the perimeter island. Direction of set up Flowerbed While the picture shows two wires separate, they should be adjacent and no more than 1/8 inch (3 mm) from one another Perimeter wire Perimeter switch placed at least 3 feet (0.9 m) from perimeter. Wires to perimeter switch should be placed adjacent, the same as wires leading to an obstacle. Figure 1.5 Excluding Obstacles With the Perimeter Wire Direction of set up followed around obstacle 15

18 Figure 1.6 Perimeter Wire Setup Distances for Obstacles Trees large enough to allow Robomow to bump into do not require a perimeter wire around it Small tree, must exclude with perimeter wire Tree too close to perimeter, less than 4 feet (1.2m), loop out with perimeter wire Greater than 3 feet (0.9 m) Minimum distance between obstacle wire and perimeter wire = 5 feet (1.5 m) The Robomow can freely move across this section, but will still recognize the perimeter island. By allowing this, multiple obstacles in a given lawn will have little effect on free movement of the Robomow or its efficiency. Figure 1.7 Two Zone Setup Narrow passes should be at least 5.5 feet (1.7 m) between wires Large trees, OK to be treated as an obstacle and not excluded with the perimeter wire. Be sure they are at least 4 feet (1.2m) from the perimeter. Zone one Zone two 3 feet (0.9 m) wide Distance greater than 5 feet (1.5 m) 16 Closer than 4 feet (1.2 m) to perimeter wire loop out Width must be greater than 5.5 feet (1.7 m), measured from perimeter wire to perimeter wire

19 1.7 Multiple Zones/Areas As mentioned earlier, your home may require more than one zone to be set up in order for the RoboMower to work in all of your lawn effectively. Having two or even three zones does not affect the efficiency of the RoboMower and in many circumstances is more desirable than one large zone. It is suggested that each zone be no larger than what the RoboMower can mow in one full Power Pack charge cycle. Where grass areas are not contiguous, or are separated by fences or other objects, it is also recommended to make each of these a separate zone. A simple but effective and common way to set the RoboMower up is to have one zone for the front yard and one for the back yard. The side yards can be included with a front or back section, or even set us a separate zone if desired. The key is to set up the zones that will allow the RoboMower to operate with the greatest efficiency, even if it is more than one or two zones. You will quickly find that mowing the lawn in these zones is an easy process that will allow you greater flexibility in your mowing habits. The RoboMower gives you the ability to control the operating time for each zone independently, up to four different zones. In this way, if one zone needs a shorter operating time than another, it can easily be set for such a process. See Chapter 5, Operator Settings and Advanced Features for detailed information on how to use this feature. There are several ways to set up these zones, including the placement of the Perimeter Switch, depending on the actual layout of the lawn. Examples are given in figures 1.7 and 1.8. Perimeter Switch location 1 Zone A Back yard Perimeter Switch location 3 House and garage Fence Perimeter Switch location 2 Zone C Side yard Driveway Zone B Front yard Figure 1.8 One Perimeter Switch for Multiple Zones 17

20 1.8 Slopes As a general rule of thumb, any slope that can safely be cut using a walk behind mower can also be cut using the RoboMower in the automatic mode. The maximum slope limit is 15 degrees, the same as a traditional walk behind mower. Bear in mind that a 15-degree slope, though it may not sound very steep, is in fact a relatively steep slope. In cases where it is attempted to operate the RoboMower on a slope that is too severe, normally the front of the machine will try to rise from the ground surface slightly when climbing the slope vertically. The lift sensor will then activate, shutting the blades down for safety. The mower will drop back into position and may attempt the maneuver again. In any event, a slope that causes the front of the mower to raise from the ground while climbing is too steep and should not be included as part of the cutting area. In some cases, this area can be cut manually with the RoboMower, using the manual controller. Insure that you can maintain a sure and safe footing before attempting to cut a slope area in manual. If you are unsure as to whether a slope is too steep or not, attempt driving the RoboMower manually up the slope. If the front of the mower does not lift from the ground, the slope is fine to include in the cutting area. If however it does lift, exclude this section from the cutting area. WARNING!! Severe injury can occur. When attempting to mow sloped areas that are too steep for automatic operation of the RoboMower, insure that you can maintain a safe and sure footing before attempting to mow. Cut across slopes for safety. Always wear appropriate closed toe shoes when operating the RoboMower manually. 1.9 Completing The Setup Once the perimeter wire is completed and pegged to the ground, the last step to complete is attaching the Perimeter Switch to the perimeter wires and testing the setup. A properly set up perimeter will have two loose wire ends located where the perimeter set up was started; the wire end from the start of the perimeter setup and the wire end from finishing the perimeter setup. See Figure 1.9. Pull the two loose perimeter wire leads taut and peg them down to the ground, adjacent to one another, as you move away from the perimeter and towards the Perimeter Switch location (use the same pegs to attach the two wires from the lawn to the Perimeter Switch location). Note that the wires are adjacent and touching leading from the perimeter to the Perimeter Switch. Peg firmly to the ground leading away from the perimeter and towards the perimeter switch location Two wire ends from perimeter setup. Perimeter witch > 3 feet (1m) from perimeter. Figure 1.9 Completing Perimeter Wire at Perimeter Switch At the location of the perimeter switch, cut the two loose perimeter wires so they are of equal length, removing any excess wire. Strip back ¼ inch (6 mm) of insulation from each wire end. Insert the wire ends to the connector (either wire to either screw, as there is no polarity) and tighten the screws as shown in figure

21 Strip back ¼ inch (6 mm) of insulation from each wire end and insert each perimeter wire end into hole of connector. Using a small flat blade screwdriver, tighten these two screws to secure the perimeter wires into the connector Figure 1.10 Inserting and Fastening Perimeter Wire to Connector Take the Perimeter Switch and squeeze the tabs on both sides of the Perimeter Switch as shown in figure 1.11, and remove the back cover from the Perimeter Switch. Insert the 3 C-cell batteries in the battery holder as shown in Figure 1.12 and reassemble the Perimeter Switch. Figure Squeeze to remove cover Figure 1.12 Inserting Batteries 1.10 Test the Perimeter Switch Plug the perimeter wire connector into the Perimeter Switch (see figure 1.13) and press the ON button. A small flashing green light next to the ON button indicates the system is on and functioning correctly. The Perimeter Switch also has an indicator for low batteries and for a disconnected/broken perimeter wire. Figure ON button and indicator light Low battery indicator light Disconnected/broken wire indicator light Figure 1.13 Plug the plot connector into the Perimeter Switch Figure 1.14 Perimeter Switch Operating Panel 19

22 The Perimeter Switch has an automatic shutoff feature, eliminating the need for you to turn it off after each use. It will shut itself off after 5 continuous hours of operation. You can expect a good set of alkaline batteries in the Perimeter Switch to last most, if not all, of a normal cutting season. You may manually turn the perimeter switch off by pressing the ON button continuously for 3 seconds. A beep will be heard after the three seconds, indicating you may release the button and the switch is off Placing The Perimeter Switch The Perimeter Switch connector is designed for quick and easy disconnection, a flexible feature should your lawn require more than one plot. You easily disconnect it by simply pulling the connectors apart. This allows you to easily move the perimeter switch between plots. The Perimeter Switch also comes with a large stake that fastens to the back of the perimeter switch, making movement from one plot to another easier by allowing you to disconnect the switch and move it with the stake still attached. Simply stick it into the dirt and plug it into the perimeter wire for each plot. See Figure 1.15 Another placement option is to mount the switch onto a vertical surface, such as a wall or deck railing. There are three small bosses on the back of the switch cover in order to mount it in this way. Use #6 or #8 sheet metal screws, or equivalent. See Figure In any event, the switch must be mounted vertically in order to maintain its water resistance and preferably in a dry and sheltered location. The Perimeter Switch MUST be mounted vertically in order to maintain its water resistance Mounting the Perimeter Switch using three mounting bosses on back cover Disconnect Perimeter Switch connector and move switch to new plot.

See Figure 2.2 Carefully lower the Power Pack into the RoboMower. The RoboMower now will power up (wake up). The Power Pack is charged at the factory and has plenty of power to perform the initial setup and test run. However, after the initial set-up process is completed the Power Pack needs to be charged for a full 20 hours before the first operation. See Chapter 4, Power Pack Charging & Power Management. Contacts Insert the Power Pack fuse into the fuse holder. The fuse can be inserted in either direction Figure 2.2 Inserting Fuse Into Power Pack 21

24 2.2 Using The Manual Controller The RoboMower is equipped with a Manual Controller. It enables you to manually drive and operate the mower. To get started on using the Manual Controller, study figure 2.3 to view the various operating controls and their functions. Refer to Chapter 5, Manual Operation for full details regarding use of the Manual Controller. 1. Manual blade engagement button 2. LCD display window 8. Navigation button 7. Manual drive speed control fast/slow 3. Clear/cancel button 4. GO/Start button Figure Manual Controller Layout 6. Scroll arrows for menu selection 5. Stop button 1. Manual blade engagement button manual engagement of the blades requires two distinct button operations in order to operate. This is called a two-step OPC design, where OPC stands for Operator Presence Control. If at any time you release the blade engagement button the blades will stop and the previous steps must be repeated. See section 3.8 for full details on manual mowing. 2. LCD window display displays the text messages using a Liquid Crystal Display (LCD). Also shows current battery status. If exposed to direct sunlight for extended periods, the display may be difficult to read. Move it to a spot out of direct sunlight or otherwise shade the display and it will quickly return to normal. 3. Clear/cancel button as described in item 1, this button is used as part of the two-step button sequence in order to engage the blades in manual mowing. In addition, this button is used to cancel a selection shown in the LCD window when making user selections. It is also used as a means to reverse back out of the menu options that can be accessed in user options, returning you to the main screen. 4. GO/Start button the main operating button for automatic operation. In addition it is used as a button for making or confirming selections made under user options in the LCD window. 5. Stop button pressing this button will stop all operation of the blades and wheel motors when in the automatic operation mode. It can also be used to stop an operation in progress before it has commenced. 6. Scroll for menu selection there are various options and settings available to the user, which are accessed through the Manual Controller. These menus and options are shown on the LCD window as text. Some of these items require selecting a specific option, where more than one is available. The arrow button, up and down, allows you to scroll through these different options. 7. Manual drive speed control the manual drive function is equipped with two ground speeds, fast and slow. In order to change the ground speed, press the button once to switch to the opposite speed of travel. When in fast mode, a button press will switch it to slow and vice versa. The mower must be moving using the drive control feature for the feature to work. 8. Navigation button pressing this button in the desired direction will allow manual driving of the mower. Use light pressure on the navigator pad, gently rolling it to the desired direction of travel for driving. The drive button is omni-directional in forward and reverse and constant pressure must be maintained for continued operation. 22

25 2.3 Manual and automatic operation The RoboMower is safely designed so that operation in the manual mode is prohibited unless the Manual Controller has been removed from its holder and is in the possession of the user to operate the buttons. See Figure 2.4. The manual mode is used to primarily move/drive the RoboMower into the lawn and to return it after mowing. It is also used for moving the RoboMower around to other areas if needed. As a convenience feature, the Manual Controller will also permit manual operation of the blades. Combined with the driving function, this will allow you to do light trimming and mowing in areas where the RoboMower cannot operate. Likewise, automatic operation is prohibited while the Manual Controller is removed from its holder and in the possession of the operator. The Manual Controller must be firmly seated into its holder and pivoted flush with the top of the mower before operation in automatic can proceed. See Figure 2.5. Removing the Manual Controller and using it in the manual mode. Driving the Robomow using the Manual Controller Manual Controller holder pivoted down and flushes with top of mower 2.4 Driving the RoboMower Figure 2.4 Manually Driving RoboMower Figure 2.5 Pivoting Manual Controller Flush In order to drive and move the RoboMower using the Manual Controller, place your finger in the indention of the mower at the front left of the Manual Controller and pivot it upwards, allowing you to grasp and remove the Manual Controller. Figure 2.3. Driving is accomplished by lightly pressing the directional pad with your thumb or index finger in the direction you wish the RoboMower to drive. See Figure 2.6. Forward and reverse are marked on the housing directly above and below the corresponding arrow on the direction pad. Forward and reverse are determined from a position standing at the rear of the mower. The RoboMower will turn left when the left arrow direction is pressed and right when the right arrow direction is pressed. Pressing between the primary arrows in any direction will yield a partial turning in that direction. Partial left turn forward Forward Partial right turn forward Manual Controller directional driving pad (navigation button) Left Right Partial left turn reverse Reverse Partial right turn reverse Figure 2.6 Using the Navigator Button 23

26 2.5 Setting The Cutting Height And Ground Clearance Remove the Power Pack before making any adjustments. The RoboMower has two basic adjustments, cutting height and ground clearance. When using the high cut blades, the cutting height is adjustable from approximately 1.5 inches to 3.5 inches (3.8 cm 8.9 cm) and with the low cut blades from 1 inch to 2.5 inches (2.5 cm 6.4 cm). By using the small wheels the minimum cutting height received is 0.75 inches (20 mm). The ground clearance has two (three when using the small wheels) adjustment positions. The cutting height adjustment is located at the front wheel and is controlled by rotating the front wheel hub in or out, which effectively causes the front wheel to be raised or lowered. See Figure 2.7. Rotate the front wheel hub in (lower) or out (higher) to adjust the cutting height. Each click represents about 1/4 inch (6 mm) in height of cut. Rotate this direction for higher cut Rotate this direction for lower cut Figure 2.7 Adjusting the Height of Cut WARNING!! Severe injury is possible. Always remove the Power Pack when attempting to adjust the height of cut or otherwise lifting the mower off the ground. Never lift the mower or attempt to adjust the cutting height during operation. Blades are very sharp and severe cuts or lacerations are possible. When working around or near the blades always wear heavy gloves. The ground height adjustment is located in the Power Pack compartment of the mower. See Figure 2.8. It has two positions, upper and lower. (RL550 Europe has three; upper, lower and middle) The lower position (closest to the bottom of the Power Pack compartment) provides the highest level of ground clearance while the upper position (farthest from the bottom of the Power Pack compartment) provides the lowest level of ground clearance. See Figure 2.9. It is typically recommended to adjust the rear ground clearance for maximum clearance, which is the setting closest to the base of the Power Pack compartment. European lawns and lawns where the grass is cut at extremely low levels of less than 2.0 inches (5 cm) may find that adjusting the ground clearance to the minimum level may work best for them. Rear ground height adjustment is located in the Power Pack compartment. To adjust ground clearance, pull out on tab as shown and slide tab up or down. Figure 2.8 Ground Clearance Location Figure 2.9 Adjusting Ground Clearance 24

27 2.6 Set Country and Perform One Time Calibration The RoboMower uses a sophisticated navigation system that utilizes an on-board compass type device, which responds to the magnetic poles of the earth. Magnetic North can vary from one point on the earth to another, based on geography. In order to accommodate this variance, it is necessary to calibrate the compass device to the area of the earth where the mower is being used. This is a one-time process and need not be repeated unless the mower is moved several hundred miles from its present location. See Figure The calibration process is simple and the RoboMower is designed to ask you to perform this step before it can ever be used in the automatic mode. Remove the Manual Controller from the holder and drive the RoboMower to a smooth and horizontal area inside the lawn. If the grass is extremely high, adjust the height and ground clearance adjustments to their highest position relative to the ground. Position the RoboMower in the center of the area and insert the Manual Controller back into the holder and pivot the holder flush with the top surface of the mower. You may have to help push the coiled cord attached to the Manual Controller into the space below the controller in order to get the holder flush with the top. Turn the Perimeter Switch on to activate the perimeter wire, as it must be in operation to perform this process. You will now be at the first display as seen in Figure Follow the sequence pictured in Figure 2.10 to complete this process. During the calibration process, the RoboMower will begin rotating slowly in a circle, pausing from time to time. The RoboMower can make up to four complete circles during this process, pausing several times for several seconds each time along the way. The LCD panel will have a text message of Wait flashing on and off during this process. Only when the text message, Test Passed Press C is shown on the LCD is the process complete. Press the C button to return the LCD text message back to the main menu message of Zone A MAX. Though unusual, it is possible that the first attempt to calibrate can fail, where the text message on the LCD is Retry Elsewhere. While unusual it does not indicate a problem with the RoboMower. It simply means that something nearby is introducing too much interference to get an accurate calibration. It can be metal objects or even underground wires. Once the calibration is completed, this interference will not cause any problems to the RoboMower. To re-calibrate, simply drive the RoboMower to another smooth level spot at least feet (3-4.5 m) away from the spot first used, and repeat the same steps for calibration. Once calibration is successful, the message requiring you to calibrate will never be seen again. 25

29 2.7 Test the Perimeter Wire Position for Edge Mowing: As mentioned in Chapter 1, it is best to test the position of the perimeter wire on edge mowing to determine if any small adjustments need to be made to the wire position before driving the rest of the wire pegs into place. Because the bumpers are active during edge mode, if the wire is positioned too close to a wall or other fixed object, the bumper will activate when striking the object then move off the edge to bypass the obstacle, retuning to the edge. There are other scenarios where the wire may need to be adjusted, such as along flowerbeds or along street edges where there is a drop off at the curb. Manually drive the mower approximately 3 feet (1m) from the perimeter wire. Position the RoboMower towards the perimeter wire (See figure 2.11) along any edge in the zone. Insert the controller back into the holder; making sure it is pivoted down flush with the top. Insure the Perimeter Switch is turned on. Figure 2.11 Testing the Perimeter Wire Position Position the RoboMower towards the wire Press the down scroll arrow for the User Options and follow the instructions below (Figure 2.12): Manual User Options Press GO Figure 2.12 Wire Position menu option User Preferences Zones setup Wire position Wire position to test Press GO Scroll down twice to Wire position option Press GO Press GO Walk along the side of the RoboMower while it is following the edge. At any point where the mower position is too far to the outer edge of the lawn area, note this area and slightly move the wire towards the interior. For example, if the bumper of the mower is hitting the wall of your home while trying to mow the edge, the wire is too close to this edge and needs to be positioned more towards the interior of the lawn, and away from the wall. Conversely, if the mower is not mowing close enough to fixed objects like walls or fully onto adjacent and level areas such as a driveway, the wire needs to be positioned farther from the interior of the lawn, out towards the wall or driveway. Reposition the wire along each section where a change needs to be made, usually moving it only a little each time, and then test the edge mowing in this area once again. Repeat this process for the entire edge until it can complete the perimeter without striking any object and you are satisfied with the cutting distance over onto adjacent level areas. Once complete, walk back along the perimeter and add in wire pegs to those areas of the wire where it is not pulled down below the level of the grass tips and close to ground level. 27

30 Chapter 3 Manual and Automatic Operation 3.1 Activating The Perimeter Switch The RoboMower cannot operate unless the Perimeter Switch is turned on and the mower is on the inside of the active perimeter. Locate or connect the Perimeter Switch to the zone, which you would like to mow. Press the ON button to turn on the switch. You will hear one short beep when the switch is first pressed, indicating it is on. To verify switch operation, there is a green LED located next to the ON button that will flash when operating properly. If an intermittent beeping is heard shortly after turning the switch on, there is a problem with the batteries or the perimeter. Look to see which red LED is flashing to determine which is the problem. You must correct the problem before the RoboMower will operate automatically. In a case where you have forgotten to turn on the Perimeter Switch the LCD on the Manual Controller will display No wire signal message (Figure 3.0), reminding you to turn the switch on. If a cut wire indicator is flashing be sure you connected the Perimeter Switch to the perimeter wire using the small green connector. If the low battery light is flashing, insert fresh c-cell alkaline batteries. If this does not correct the problem, refer to Chapter 6, Text Messages and Troubleshooting for further help. No Wire Signal Figure 3.0 No Wire Signal Display WARNING!! Serious injury or death can occur. This machine has sharp rotating blades. When operating in automatic mode, keep children, pets and bystanders away from mower. When operating automatically, do not leave unattended if children, pets or other persons will come in contact with the mower during operation. Never allow persons or pets to ride on this machine or block the path of travel. 3.2 Positioning RoboMower On The Lawn Remove the Manual Controller from its holder and drive the RoboMower into the lawn area to be cut. The manual driving speed of the RoboMower has two speeds, slow and fast. You may select the opposite speed by simply pressing the Speed button once while in the process of driving the mower. Position the RoboMower at least 6-8 feet ( m) from any straight length of perimeter wire, with the front of the mower pointing to the perimeter wire. Figure 3.1. Figure 3.1 Positioning RoboMower on Lawn Starting point Front pointed to perimeter wire 3 feet (1 m) 28

31 3.3 Edge Mowing Chapter 3 Page 28 The first mowing chore for the RoboMower is mowing the edge. By edge, we mean the outer perimeter of the active zone the RoboMower is working within. This is essentially where you placed your perimeter wire in the wire set-up. Edge mowing provides a clean even cut around the perimeter and helps to minimize the amount of trimming along walls and other obstacles. The RoboMower will always mow the edge in a counter-clockwise direction. Figure 3.2. The RoboMower will automatically find the edge (perimeter), mow it and then turn off into the lawn to complete the mowing. Figure 3.2 Edge Mowing Starting point In order to start the automatic mowing, including the edge mowing, the Manual Controller must first be placed back into the holder and pivoted down. Once the controller is placed into position, the LCD will display a text message indicating it is in the automatic mode. Figure 3.3. Figure 3.3 Automatic mode display Zone A: 1:40 Once the message is displayed, press the green GO button once to start the automatic mowing sequence. A short warm up sequence will begin, the operating lamp will begin flashing and then the blades will start rotating. The LCD display will change to the text message in Figure 3.4. Once it reaches the edge, it will generally straddle the wire at about the center of the mower. It will now begin mowing the edge, completing one to two complete passes around the perimeter. At the point the RoboMower is satisfied the perimeter has been cut, it will stop and then rotate towards the inner area of the lawn. It will then drive into the lawn and begin what is called the scanning process. This is simply the methodical mowing of the lawn using the advanced navigation system of the RoboMower, RoboScan. The LCD display will change to the text message in Figure 3.5. Edge RoboScan2 Figure 3.4 Text on Edge Mowing Mowing RoboScan2 Figure 3.5 Text in Scan Mowing 3.4 Scanning (Mowing) The scanning process is simply a process whereby the RoboMower is systematically moving across your lawn while it is mowing. It will generally move in a right to left direction and then a left to right direction. During this process, it will also make other turns and moves in order to navigate itself back and forth across the lawn. Keep in mind that the RoboMower will not mow all the grass on its first pass; in fact it will leave uncut grass in between many of the legs it makes. This is expected and is entirely normal. These uncut areas will be cut on subsequent passes of the RoboMower across the lawn. Just like a dishwasher, wait until the job is finished before you can appreciate the results. The RoboMower will continue to run for the amount of time selected or for the default MAX time, which is generally 1.5 to 3 hours, depending on RoboMower model, grass type and condition. See Chapter 5, Settings and Advanced Features for more detail on setting operating time. 29

32 3.5 Skipping Edge Mowing The RoboMower provides a means that will allow you to skip the edge mowing process and start directly with the scanning (mowing) process. In order to do this, simply press the GO button two times at the initial startup of the mower. Pressing GO the second time immediately following the first press will tell the mower to skip mowing the edge. See Figure 3.6. You may start the mower anywhere within the perimeter that you choose, but at least 3 feet (1m) away from the closest perimeter wire. Zone A: 1:40 Ready to start in automatic mode display. Pressing GO will take you to the next screen. again to Skip Edge To skip the edge mowing, press GO once more, otherwise it will begin in edge mow. Figure 3.6 Text Message After Pressing GO 3.6 Mowing Complete When the RoboMower has operated the allotted time, it will simply stop in the lawn, waiting for you to drive it back home and plug it into the Power Supply, ready for the next mowing session. As discussed earlier, there will always be plenty of Power Pack energy available to drive the mower back to the area where it is stored and charged. See Chapter 4 Charging for more on charging instructions. The LCD will display a text message as seen in Figure 3.7 if the mowing time is set to the default time of MAX or the message as shown in Figure 3.8 if the mowing time has been selected to any time other than MAX. Recharge Battery Time Completed Figure 3.7 Text Message After MAX Mowing Figure Text Message After Mowing Pre-set Time If the RoboMower has completed its mowing and it is more than 20 minutes before you arrive to move it, the LCD screen will be blank. The RoboMower will shut itself down into a sleep mode after 20 minutes of inactivity at all times. This is an energy saving feature. Pressing the GO button or removing the Manual Controller from the holder will wake up the RoboMower and display the message that was on the LCD when it went into sleep mode. In this case, either the message in Figure 3.7 or Driving and Navigation The RoboMower is equipped with a Manual Controller that allows you to easily drive it from the lawn back to a storage area when not in use. It also allows you to manually engage the mowing blades, and while driving, to trim small areas of grass. 30

33 The Manual Controller can only operate in manual mode when removed from the holder, which holds it in place during automatic operation. For safety it is designed in such a way that manual operation is prohibited while in the holder and automatic operation is prohibited when removed from the holder. You will also notice that the Manual Controller contains the keypad for starting automatic operation as well as the emergency stop. To access manual operation, remove the Manual Controller as seen in Figure 3.9. The controller is designed to be grasped by both hands while operating, with the blade control buttons to the left side and the driving/navigation button to the right. Once the controller is removed, driving the RoboMower from place to place is very simple. Using your thumb or index finger of your right hand, gently press the navigator button in the direction you want to drive. The button is omni-directional, allowing for slight turns as well as sharp turns, all the way to a complete circle. It takes little pressure to activate the drive motors using the navigator button, and use is best obtained by lightly rolling your finger in the direction you wish to drive. Continuous pressure is required to drive, so once released the mower will cease movement. Figure Manual driving has a slow and fast speed. You can change the speed to the other level at any time by pressing the speed button once while driving. Another press and the speed returns to the opposite level. See Figure WARNING!! Serious injury can occur. Always wear appropriate footwear when driving and using RoboMower in the manual mode. Keep a safe distance from the mower when operating it manually. Note that the reverse driving direction is from the point of view standing at the rear of the mower. Always look behind when you are using the reverse direction drive. Do not operate RoboMower in areas not suitable for manual operation or on slopes where a sure footing is not possible. Cut across slopes for safety. Do not drive RoboMower with persons sitting on it and do not manually operate within 10 feet (3m) of other persons or pets. 3.8 Manual Mowing (not available in RL350) You have the ability to manually activate the blades on the RoboMower in order to trim small areas. After the blades are activated you may drive the mower using the navigator button and you may cut in any direction the navigator button will operate, including reverse. The manual mowing operation on the Manual Controller is a two-step OPC (Operator Presence Control) type system for safe use. It requires two separate and independent steps to activate the blades and once activated, release of the button will immediately stop the blades. At any time the blades have been stopped, it will require the OPC activation process to be repeated. During manual mowing operation, activation to any bumper sensor will shut down the blades. Figure

35 Chapter 4 Charging 4.1 Charging Of all the areas regarding the RoboMower, proper charging of the Power Pack is second only to safety in importance. Failure to follow the charging guidelines will result in poor performance and a short Power Pack life. After the completion of any daily cutting session it is very important to bring the RoboMower to its storage area and plug it into the Power Supply as soon as possible, preferably within 6 hours from the time it stopped. The standard Power Supply, Figure 4.1 is actually an indoor power supply, where the voltage output is DC and the current flowing to the Power Pack for re-charging is regulated inside the mower. The charging system and Power Pack are designed such that they can remain plugged in at all times of non-use without concern to over charging, over heating or damaging the Power Pack. In fact, it is the preferred way to maintain your Power Pack, always keep it plugged into the Power Supply between uses. The power supply will re-charge the Power Pack from the Recharge Battery level in approximately 20 hours, depending on conditions. There is a fast charger available as an accessory. See the accessories available for your RoboMower in Chapter Charging Using the Standard Indoor Power Supply Connected to the Charging Socket Connect the Indoor Power Supply to a regular household receptacle, 120 Volts AC (models outside the US utilize 230 volts mains power) and the output lead of the Power Supply, Figure 4.2, into the charging socket, located under the Manual Controller holder, Figure 4.3, and the charging process will begin. Lightly pivot the Manual Controller down, allowing it to rest gently on the charging cord. DO NOT attempt to force the Manual Controller all the way to the flush position. The RoboMower Power Supply is designed for indoor dry use only. Do not charge the RoboMower where wet contact is likely. WARNING!! Shock hazard. Injury or electrocution can occur. The RoboMower Power Supply is designed for indoor use in dry locations only. Never use the Power Supply or charge the RoboMower in areas where extreme dampness or wet contact is likely. Never use a Power Supply when the leads are damaged. Use only the recommended Power Supply with your RoboMower. Indoor Power Supply 120 volt shown Figure 4.1 Power Supply plug output lead Figure 4.2 Power Supply connector socket Figure

36 The LCD on the Manual Controller will display the text seen in Figure 4.4 and the battery icon will continually move from empty to full to show the charging. Once the battery is fully charged, the message will change to that as shown in Figure 4.5, reminding you to keep it connected to the Power Supply until the next use. Charging is such an important aspect for assuring good performance and Power Pack life that a special alert and power management system is incorporated into the mower to remind and alert you when the proper charging process is not occurring. Charging Figure 4.4 Ready Keep Charging Figure 4.5 Battery Icon The importance of proper charging and maintenance of the RoboMower Power Pack cannot be stressed enough. Failure to follow the recommended charging procedures will result in poor performance of the RoboMower and shorten the life of the Power Pack. When the Power Supply plug is disconnected from the Manual Controller holder, the following message will be displayed on the LCD screen. See Figure 4.6. Press any button on the Manual Controller and the main screen, 'Manual User Options display will appear on the LCD. Keep Charging If Not Used Figure 4.6 LCD Display when disconnected from Power Supply Important! The Power Supply is IN DOOR USE ONLY, place it in a sheltered place, dry location, which is well ventilated and not exposed to direct sunlight 4.3 Power Management & Charging Alerts The RoboMower is equipped with a sophisticated power management and alert system that operates at two levels; 1) to use the energy provided from the Power Pack in the most efficient manner during operation and non-operation and 2) to help remind or alert you when the charging system is not being used properly in order keep the Power Pack in top condition for peak performance and service. Level one is a somewhat transparent level to the user, but under certain conditions will communicate information to the level two system in order to alert you that something regarding the Power Pack and charging system needs your attention. It is the level two system that communicates to you through LCD messages and audio. The basic assumption of the system is that the RoboMower will be connected to a Power Supply at all times when a Power Pack is inserted in the mower, except when in operation. This assumption is made because this is the only way to insure that the Power Pack will always deliver satisfactory performance during operation and will also provide a reasonable service life. Given this, the system alerts the user at several different levels and frequencies when this is not happening. In addition, the system can also alert 34

37 the user when something has interrupted the charging operation, such as a loss of power to the Power Supply for example. The Power Pack should be fully charged before initiating any operation. In addition, you should have examined the mower before operation to look for problems that may cause excessive energy consumption and thereby less than optimum run-time. Examples include dull blades or heavy grass accumulation around the blades. Other examples can be found in Chapter 6 Text Messages and Troubleshooting. First and foremost, insure that the Power Pack is indeed fully charged before putting it to work. Only when the LCD displays the message in Figure 4.5 is the RoboMower fully charged and ready for mowing. And lastly, use the RoboMower for the job it was designed to do, cutting normal levels of grass growth. The RoboMower can operate under two different run-time scenarios; 1) operate the maximum time allowable by the system, where this time is dictated solely on the remaining level of energy in the Power Pack and 2) where the run-time is set to operate a fixed amount of time set by the user, such as one hour for example. Maximum operation will always display Recharge Battery after the cutting session and a fixed time will display Time Complete after the session. Under either of these operating scenarios it is important to retrieve the RoboMower and place it on the Power Supply as soon as practical, preferably within 6 hours from the time it stops operation. The Recharge Battery level has a higher priority in the power management system than Time Completed for the obvious reason that the Power Pack voltage is at a lower level. For this reason, immediately following a Recharge Battery message the RoboMower will emit a buzzer sound every 30 seconds for the next 20 minutes in order to alert you that the mowing session is completed and it is now time to re-connect the Power Supply to the RoboMower. If the RoboMower is not connected to the Power Supply within the next 21 hours, a higher-level alarm will sound. If the Power Supply is still not connected after this alarm series, the mower will enter a deep sleep mode to conserve power. If the RoboMower enters a deep sleep mode, the Power Pack must be removed for 10 seconds and then re-inserted in order to wake up the RoboMower. However, if the mower reaches this level and the Power Supply is not connected soon, you risk causing poor performance and service life to the Power Pack. Similar alarms will alert you to connect the Power Supply if not connected after a fixed time, when operating under fixed run-time settings. Lastly, if the Power Supply is disconnected, even after the fully charged message, the alert system will operate to remind you to keep the Power Supply connected until ready to use for mowing. 4.4 Off-season storage When preparing the RoboMower for off-season storage, first fully charge the Power Pack and then store it separately from the RoboMower in a dry location where the temperature will not drop below -20 ºC (-4ºF). Recharge the Power Pack every three months while in storage. Important! For more details regarding the winter storage please refer to section

40 Learn Edge The default distance for edge mowing is approximately 1.5 to 2 rounds around the perimeter. This feature allows the user to learn a specific distance in each operating zone in order to cause the mower to cut the edge a specific distance, such as one full round. It will remain as a learned distance until the edge is re-learned or the factory default edge is selected. It should be done when the Manual Controller is in the holder and flush with the mower top. Learn Edge gives you the ability to have the RoboMower learn the distance around the edge. Figure 5.6.

50 Chapter 8 Maintenance and Storage Recommended Maintenance Schedule Maintenance Service Interval Each Use Maintenance Procedure Check and remove grass clippings and dirt from the mowing deck if necessary, particularly when mowing wet and damp grass (refer to section 8.1) Charge the power pack after every use. 50 Hours Remove Power Pack and check any damage on the blades (refer to section 8.2) Hours 8.1 Mowing Deck WARNING! Replace the blades; replace them more frequently if the edges dull in rough or sandy conditions (see Figure 8.2). Remember to restart the automatic blades replacement reminder after every time the blades have been replaced (refer to section 8.2). The underside of the mowing deck needs to be inspected, and cleaned if necessary, between operations. The RoboMower is a dedicated mulching mower and may accumulate clippings under the mowing deck, particularly when mowing wet and damp grass. Figure 8.2! Serious injury can occur. Always remove Power Pack before lifting mower. Blades are very sharp and can cause severe cuts or lacerations. Always wear heavy work gloves when working with and around the blades. Never use a damaged or broken blade. Use only sharp blades. Most grass accumulation can be removed using a small wooden stick or similar object. Carefully scrape the collected grass debris from under the mowing deck. If necessary, remove the blades to gain better access to the mowing chambers in order to clean them. Do not place the mower upside down, damage to the Manual Controller can occur. Instead, lean the mower against another surface to gain access to the mowing deck area. NEVER use a water hose or other type of liquid sprayer to clean the underside of the mower. Component damage can occur. Use only a damp or wet cloth to wipe the surface clean after scraping. 8.2 Blades The cutting blades of the RoboMower should be examined for damage between operations. Replace any damaged blade found. Only use sharp blades. Replace blades at least once per season, more often if they have been severely dulled. It is recommended to replace all three blades for best performance. Machine sharpening is not recommended, as a good balance cannot be achieved after machine sharpening. See Figure 9.1. RoboMower has an automatic reminder to replace the blades after every 200 hours of operation. Replace blades every 200 hours message appears and pressing the GO button will clear the message and enables the operation of RoboMower. 48

51 Whenever replacing the blades, it is recommended to restart the counter of the blades replacement reminder by choosing the Blades replaced option under the User Preferences menu and press the GO button again to clear the reminder.
